WORKSHOP PAPER
Applied Mathematics to Simplify Imager and Camera Analyses
Abstract
Discussed in this paper are three extremely helpful techniques in the analyses of imager and camera performance. The first topic is an extension to the well-known photon shot noise curve. It is a straightforward method to determine any arbitrary transfer function f(N) from pixel-to-camera output. Next, the design of a µ-lens is usually executed as a function of Chief Ray Angle (CRA). But performance is practically measured with a lens and a given f-number range. The method offered converts the f-numbers into a set of CRA numbers with which the µ-lens efficiency η(CRA) can be determined as a function of CRA. The third topic entails the application of a 2-dimensional histogram to investigate the dependence of all pixels in an imager on one parameter, like temperature, supply voltage, or time.Keywords
